END-THRUST BEARING.

Application filed January 22, 1927. Serial No. 164,050.

. This invention relates to an end thrust bearing for ,WOIIII drives,the general object of the invention being to relieve the load on theordinarybearings of the worm, V The invention is especially adapted foruse in trucks having worm drives, but it can be lubricated.

This invention also consists in certain other features of constructionand 1n the combination and arrangement of the several parts,

5 to be hereinafter fully in the accompanying cally pointed out in theappended my invention in detail, ref had to the accompanying Indescribing erence will be 3 drawings wherein like characters described,illustrated drawings and specificlaim,

denote like u v or corresponding parts throughout the sev:

eral views,

) Figure 1 1s a view and in which showing portion of a worm drive, withmy invention in use thereon. Figure 2 is a section on line 2- -2 ofFigure-1.

In these vlews,

bearings at one end shown at'5.

It is'the object these hearings of 1 indicates the housing tr the wormshaft 2', and 3 indicates the ing of the worm gear housof the shaft- 2'being of my invention to relieve the end thrust of the worm .shaft whichoften causes said bearings 5 to burn up and sometimes In carrying out myto break the housing. invention, I provide a closing plate 6 for one endof the housing 1,

said plate being 4o shoulder 7 and a s rovided with an interior oulder 8is formed on the end of the shaft 2 and between these shoulders I placethe thrust bearings which coneist of the race rings 9 bearing againstthe.

4, the anti-friction in adjusted position.

An oil passage 13 is formed in the cover plate 6 and is arranged toconduct lubricant on to the bearings 10. A cup 14. is threaded in theouter part of the passage to contain the lubricant.

From the foregoing it will be seen that I have provided simple means forpositioning end thrust bearings at the end of a worm shaft to take theend thrust thereof, with means for adjusting the bearing without re- 1moving any parts and also to provide means for lubricating the bearings.I

,It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it tobe understood that I may 7 make changes in theconstruction and in the combination and arrangement of the severalparts,;, provided that such changes fall within the scope of theappended claim.

What I claim is: e In combination with aworm shaft and its housing andanti-friction bearings between the end of the shaft and the housing, ashouldered cover plate at one end of the housing, the shaft having areduced end forming a shoulder, ball. races placed against the shoulderson the cover plate and the shaft, said races surrounding the reducedend/of the shaft, balls between theraces, an adjusting nut carried bythe cover the bearings and means or locking the nut In testimony whereofI aflix' my signature.
